DETAILED DESCRIPTION OF THE INVENTION
An automobile grab box door according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 3, the grab box 9 housed in the cavity 1 b provided in the instrument panel body 1 a of the instrument panel 1 is integrally provided with the box 9 a inside the door 2, and the lower end of the door 2. The portion is supported by the instrument panel main body 1a by the hinge 9b and is opened from the closed position on the same plane as the front surface to an open position inclined upward from the horizontal direction.
[0010]
A handle 11 is housed in a recess 2a formed in the upper part of the door 2, and on both sides thereof, as shown in FIG. 2, a door is attached to a side surface 2b of the recess 2a and a bracket 2c protruding from the door 2. The inner end portions of the rods 10 extending along the axis 2 and rotatably supported are connected to each other. Accordingly, when the door 2 is pulled backward by a finger in the gap 2d at the lower end portion of the recess 2a, the rod 10 is rotated.
[0011]
As shown in FIG. 1, a coil spring 12 is tightly wound around the outer end of each rod 10 so as not to slip and rotate with respect to the rod 10, and one straight non-winding end 12 a thereof. Is locked to the door 2. The other non-winding end portion 12b is an arm-shaped spring that passes above the rod 10 in the winding direction and extends toward the front of the vehicle. The end of the lock lever 13 extending in the width direction is attached as a lock piece. A spring retainer 15 is attached to the outer end of the rod 10 to hold the non-winding end 12b from above. This pressing angle is set so that the non-winding end 12b is directed to the front and upper side of the horizontal position at the closed position of the door 2.
[0012]
An exit portion 17a that opens toward the rear of the vehicle in a side region facing the lock lever 13 in the hollow portion 1b of the instrument panel body 1a that houses the box 9a, and a lock portion that enters the vehicle forward from the exit portion and rises. An L-shaped lock groove 17 having 17b is formed. The side surface of the lock groove on the handle side is opened to allow the lock lever 13 to enter in the vehicle width direction opposite to the handle side. The upper surface area including the upper surface of the outlet portion 17a inclined downward toward the front of the vehicle and the space of the outlet portion 17a along the upper surface constitutes the inlet portion 18 of the lock lever 13. On the side surface of the box 9a, there are formed a side portion 9c that abuts on the side receding surface 1c of the cavity portion 1b, and a descending portion 9d that escapes the tip portions of the lock lever 13 and the spring retainer 15.
[0013]
Thereby, when the door 2 is closed, the corner portion 13a at the front surface of the curved upper surface of the lock lever 13 comes into contact with the periphery of the inlet portion 18 of the lock groove 17, and the non-winding end portion 12b is bent downward. When the upper surface of the inlet portion 18 which is also the upper surface of the outlet portion 17a is automatically slid, and then the restraint by the upper surface of the inlet portion 18 is released by the L-shaped lock portion 17b, the lock portion 17b is lifted by the elastic return force upward. Enlist in. Further, the front-rear width of the lock portion 17b is set to be slightly wider corresponding to the front-rear width of the lock lever 13 so that it does not fluctuate in the front-rear direction when the lock lever 13 is engaged with the lock portion. The state is stabilized.
[0014]
On the other hand, when the door 2 is opened, by operating the handle 11, the spring presser 15 is rotated downward via the rod 10 to lower the lock lever 13 to the height position of the outlet portion 17a, and the handle 11 is moved rearward as it is. When pulled, it is opened via the outlet 17a.
[0015]
The operation of the lock mechanism of the grab box door configured as described above is as follows. In the normal state in which the door 2 is closed, the lock lever 13 is engaged with the lock portion 17b of the lock groove 17 in a locked state in which front-rear movement is restricted. Further, the door 2 is urged forward by the non-winding end portion 12a in a state where the rod 10 has a sufficiently large sliding resistance with respect to the coil spring 12, and thereby the side toward the side receding surface 1c. By the contact of the part 9c, it is stably held in the closed position in the same plane as the front surface of the instrument panel 1.
[0016]
When opening the door 2, when a finger is inserted into the gap 2 d at the lower end of the handle 11 and the handle 11 is rotated upward and backward, the rod 10 rotates and the spring retainer 15 is unwrapped at the end of the coil spring 12. 12b is bent downward. As a result, the lock lever 13 is lowered to the height position of the outlet portion 17 a, and the door 2 is pulled as it is to release the lock lever 13 from the lock groove 17. When the handle 11 or the door 2 is pushed forward at the time of closing, the lock lever 13 abuts on the periphery of the inlet portion 18, thereby moving forward along the inlet portion 18 while bending the non-winding end portion 12 b downward. Then, the lock portion 17b releases the restraint by the inlet portion 18 and moves upward to be locked.
[0017]
Further, instead of the lock lever, as shown in FIG. 4, the lock piece 20 can be protruded forward without intentionally extending in the lateral direction. As a result, when the door is closed, the lock piece 20 abuts the upper periphery of the entrance / exit portion of the lock groove at the corner portion 21, and the non-winding end portion 12 b of the coil spring is bent downward to slide into the entrance portion. Unlike the above-mentioned part, the upper part 22 is automatically locked with respect to the non-winding end part 12b of the lock piece 20 by sliding along the upper surface parallel to the non-inclined bottom surface and returning upward to the coil spring. Enroll in the department. In this case, the side surface of the lock groove on the handle side can be optionally closed, and the width of the lock piece can be reduced. In some cases, the arm-like spring is not a non-winding end portion of the coil spring, but is constituted by a leaf spring, and the handle can be biased by another spring.
[0018]
5 and 6 show a locking mechanism according to another embodiment, and the same or equivalent parts as those described above will be described with the same reference numerals. An exit portion 27a that opens toward the rear of the vehicle in a side region closer to the lower side than the rotation path of the lock lever 13 in the hollow portion 1b of the instrument panel main body 1a, and enters and rises from the exit portion to the front of the vehicle. A lock groove 27 having an L shape with the lock portion 27b and having a side opening so as to allow the lock lever 13 to enter from the handle side vehicle width direction is formed. In addition, an entrance portion 28 is formed in the side surface region on the vehicle rear side of the lock portion 27b as an inclined surface that is inclined rearward from the side end 28a in the handle side vehicle width direction of the lock portion 27b in the counter handle side vehicle width direction. ing. The inclination amount of the inlet portion is set to be smaller than the width of the outlet portion 27a in the vehicle width direction.
[0019]
The spring retainer 15 sets the lock lever 13 at the height position of the inlet portion 28 by the protruding piece 15a, and the length of the protruding piece 15a is determined by the lock lever 13 along the inlet portion 28 when the door 2 is closed. It is set so that it does not come off when it is displaced in the side vehicle width direction. A corner portion 13b on the front side of the lock lever 13 on the non-handle side vehicle width side is formed in a curved surface shape.
[0020]
When the handle 11 or the door 2 is pushed forward when the door 2 is closed, the lock lever 13 comes into contact with the peripheral portion of the inclined inlet portion 27a, and the unwinding end portion 12b of the coil spring 12 is along this inlet portion. Is slid while being bent in the vehicle width direction on the handle side, and is automatically restrained by the return force of the non-winding end portion 12b at the lock portion 27b.
[0021]
When the door 2 is opened, when the handle 11 is rotated upward and rearward, the rod 10 rotates and the spring retainer 15 deflects the non-winding end 12b of the coil spring 12 downward. As a result, the lock lever 13 is lowered to the height position of the outlet portion 27 a, and the door 2 is pulled as it is to release the lock lever 13 from the lock groove 27.
[0022]
As another embodiment, the inlet portion in the side region of the rear side of the vehicle of the lock portion 27b is formed in parallel to the surroundings without being inclined, and the lock lever 13 has the curved surface of the corner portion at the edge of the inlet portion. It can also be configured such that the non-winding end portion 12b of the coil spring 12 is engaged with the lock portion 27b while being bent in the handle side vehicle width direction along the inlet portion.
[0023]
